On Solaris ld (and some other tools that use the underlying utility
libraries, such as elfdump) chokes on an archive library that has no
symbol table. The Solaris tools always create one, even if it's empty.
That bug has been fixed in the latest development line, and can
probably be backported to a supported release, but it would be nice if
LLVM's archiver could emit the empty symbol table, too.

For whatever reason ld64 requires that member headers (not the member
themselves) should be aligned. The only way to do that is to edit the
previous member so that it ends at an aligned boundary.
Since modifying data put in an archive is an undesirable property,
llvm-ar should only do it when it is absolutely necessary.

ld64 requires its archive members to be 8-byte aligned for 64-bit
content and 4-byte aligned for 32-bit content. Opt for the larger
alignment requirement. This ensures that ld64 can consume archives
generated by llvm-ar.
Thanks to Kevin Enderby for the hint about the ld64/cctools behaviours!

They should probably be created on anything that is not windows or linux, but I will
test on freebsd before changing that.
With this it is possible to bootstrap with llvm-ar instead of ar+ranlib on OS X.

No support for the symbol table yet (but will hopefully add it today).
We always use the long filename format so that we can align the member,
which is an advantage of the BSD format.

The internal shell was already threading around a 'cwd' parameter. We
just have to make it mutable so that we can update it as the test script
executes.
If the shell ever grows support for environment variable substitution,
we could also implement support for export.
